# What is a retinal tear?

A retinal tear is a break in the thin light-sensitive tissue lining the back of the eye. It often occurs when a posterior vitreous detachment pulls firmly on the retina.

## Why retinal tears matter

Fluid can pass through a tear and start to lift the retina, leading to rhegmatogenous retinal detachment if not treated. Symptoms may include new floaters, flashes and sometimes a shadow or curtain in the peripheral vision.

- Urgent assessment is needed if a tear is suspected
- Most tears can be sealed with prompt laser or freezing treatment
- Successful treatment greatly reduces the risk of detachment
- Follow-up checks look for new breaks or extension of the tear
